Re: eglibc configurability

[Mark Hatle <mark.hatle@windriver.com>]

Could you find the related init script and point me to the contents.  I don't
see any initscripts in the eglibc integration.  The only thing I see is a switch
in the locale generation between on target, on host and via QEMU.  I'm wondering
if maybe this is being triggered?
